Equivalence point determination is the point of interest in neutralization titrations. With the change in pH, the indicators which are natural, usually end up giving a sharp color change. Plant-derived pigments that are of various shades and tints generally vary in their dyeing nature by altering pH. An indicator is a substance that exhibits the property of interchangeable color of the reaction mixture when reaching the vicinity of point with the change in pH. Acid-base titration indicators are normally weak acids or bases. Hibiscus rosa-sinensis, Ipomoea biloba, Dahlia pinnata, etc. are among the typical neutralization indicators that are extracted from plants. These natural Indicators are easily available and economical. In this review, we are discussing an overview of plant extracts, and natural pH indicators, and their significance in correspondence to analytical chemistry is illustrated.</p> 2023-03-02T00:00:00+00:00 ##submission.copyrightStatement## A Detailed Insight of Monkey Pox Virus Infection in Adolescent 2023-03-03T04:52:39+00:00 Ankita Wal Garima Vishnoi Divyanshi Gupta Parul Srivastava Pranay Wal Awani K Rai <p style="text-align: justify;"><strong>Background: </strong>Smallpox-like symptoms are seen in the viral zoonotic illness known as monkeypox. In the current outbreaks being reported, the World Health Organization (WHO) claims that this is the first instance of chains of transmission being documented in Europe without known epidemiological connections to West or Central Africa. On August 7, 2022, the WHO reported a total of 27,815 confirmed cases in over 89 countries, with the majority of those affected experiencing monkeypox for the first time. The objective of this article is to provide a succinct overview of the monkey pox, its transamission mechanisms, and available preventative methods in adolescents. <strong>Materials and Methods:</strong> Several databases, including WHO guidelines, PubMed, Bentham Science, and Elsevier, were used to compile the data for the article following a thorough analysis of the various research findings connected to monkey pox infection, pathogenesis, and available treatments. <strong>Results:</strong> Monkeypox is a zoonotic orthopoxvirus that causes disease in humans similar to smallpox. Complications are more likely in children and the immunocompromised. Treatment is largely symptomatic. The first-line treatment for monkeypox, including in kids and teenagers, is tecovirimat. <strong>Conclusion:</strong> We came to the conclusion from this review that adolescents and adults both transmit the monkey pox virus. The most common sign of monkeypox in kids and teens is a rash that starts out as maculopapular lesions and turns into vesicles, pustules, and then scabs, just like diseases in adults. Children and adolescents who have been exposed to individuals with suspected or confirmed monkeypox may benefit from Post-Exposure Prophylaxis (PEP) with vaccination, immune globulin, or antiviral medicine.</p> 2023-03-02T00:00:00+00:00 ##submission.copyrightStatement## An Overview of Corrective Action and Preventive Action 2023-03-03T04:52:39+00:00 Shantanu S Thakre MP Venkatesh Rohit S Gahilod <p>Corrective and Preventive Actions (CAPA) are crucial for enhancing and raising the quality of the finished good or service. It is essential to every industry's ongoing development. In any pharmaceutical or medical device sector, the main goal of Corrective Action and Preventative Action (CAPA) is to identify any weaknesses, deviations, or failures and conduct an inquiry, and take the necessary corrective action to ensure that these issues don't recur. An approach known as CAPA also entails taking preventive actions right away to stop any incidence from happening in the first place. In a pharmaceutical company, it is both a legal necessity and a component of the broader Quality Management System (QMS). The corrective and preventive action subsystem is governed by 21 CFR 820.100, which lays out the rules (CAPA).</p> 2023-01-04T00:00:00+00:00 ##submission.copyrightStatement## Development of a Floating Drug Delivery System for Prolonged Release of Metronidazole in the Stomach for Gastrointestinal Infection 2023-03-03T04:52:39+00:00 Aanantha Kumaran Sruthi Laakshmi M Gouranga Dutta Abimanyu Sugumaran Damodharan Narayanasamy <p style="text-align: justify;"><strong>Introduction: </strong>Gastroretentive Drug Delivery System like floating tablets out performs traditional dosing forms. When compared to conventional tablets, floating tablets have higher bioavailability, higher drug concentration in the systemic circulation, and lower frequency of dose. Metronidazole floating tablets were formulated using a variety of polymer combinations by the direct compression process. Polyvinyl pyrrolidone (PVP K30), Guar gum, and Xanthum gum are the polymers employed in the composition. <strong>Materials and Methods: </strong>The drug-excipient compatibility was determined by FTIR Spectroscopy and a total of nine formulations of floating tablets have been prepared. Among these, an appropriate formulation was chosen. The angle of repose, Bulk, and tapped density of metronidazole tablet mixes were previously evaluated. Carr's index, Hauser's ratio, physical appearance, hardness, weight fluctuation, friability, floating qualities, and <em>in-vitro</em> dissolving testing were used to characterize the tablets. <strong>Results: </strong>The flow properties were found optimum in all the pre-compression parameters and hence suitable for the direct compression method. The evaluation of tablets showed a good floating effect of about 4-7 hr in almost all the formulations. The floating tablets showed drug release of more than 90% after 6 hr and hence gastric retention was achieved. The study findings revealed that formulation 3 was the best, with a floating lag time of less than a minute and more than 7 hr of retention in the gastric pH with optimum floating behavior and drug release in the stomach. <strong>Conclusion: </strong>Hence, the prepared floating system involving a combination of polymers was found to be a reliable tool for gastric retention.</p> 2023-03-02T00:00:00+00:00 ##submission.copyrightStatement## Evaluation of Sono-photocatalytic Removal of Ciprofloxacin Antibiotic Using Magnesium Oxide Nanoparticles from Aqueous Solutions 2023-03-03T04:52:39+00:00 Ferdos Kord Mostafapour Mohammadreza Radmehr Shaziya Haseeb Siddiqui Davoud Balarak <p style="text-align: justify;"><strong>Objectives: </strong>The entry of antibiotics into surface and groundwater will cause problems in the environment.

Favipiravir was crucial in the contest against the COVID-19 pandemic because of how well it treated the SARS-CoV-2 virus. It is well known that contemporary pharmaceutical analysis establishes green, stability-indicating analytical procedures. The current study aimed to develop and assess UV-spectrophotometric (zero order, first order, area under the curve) and RP-HPLC methods for estimating favipiravir in its pharmaceutical dose form, comparing them using ANOVA and an <em>in-vitro</em> dissolution analysis. A green solvents composition of methanol, ethanol, and water (25:35:40 v/v/v) is used for analysis as a mobile phase and diluent. Method A is a simple zero-order spectrophotometric method for determining favipiravir at 236 nm, and the correlation coefficient in the linearity study was found to be 0.9962, LOD, and LOQ are 0.18 and 0.55 μg/mL. Method B is a first-order spectrophotometric method for determining favipiravir at 227 nm, and the correlation coefficient in the linearity study was found to be 0.9964, LOD, and LOQ are 0.64 and 1.96 μg/mL. Method C is an area under the curve spectrophotometric method for determining favipiravir at 230 to 243 nm, and the correlation coefficient in the linearity study was found to be 0.9986, LOD, and LOQ are 0.32 and 0.96 μg/mL. Method D is the RP-HPLC method for the determination of favipiravir at the retention time of 7.216 min, a flow rate of 0.80 mL/min, column temperature of 25°C, at 236 nm, Isocratic mode, and the correlation coefficient in the linearity study was found to be 0.9996, LOD, and LOQ are 0.52 and 1.56 μg/mL. All developed methods demonstrated good repeatability and recovery with %RSD &lt; 2. The proposed established methods were assessed using one-way ANOVA. It was revealed that the F<sub>calculated</sub> value was lower than the F<sub>tabulated</sub> value, with no discernible variation in the assay results. Studies on stress degradation show that oxidation and acid degradation mostly impact favipiravir solutions. The Analytical Eco-scale verified that these methods are the greenest and most environmentally friendly, enabling the suggested approach to use an effective green analytical methodology to measure favipiravir extensively. Phosphate buffer (pH 6.4) was the best dissolution medium after analysis of the favipiravir dissolution study in several dissolution media.</p> 2023-03-02T00:00:00+00:00 ##submission.copyrightStatement## A Stability Indicating RP-HPLC Method for Simultaneous Estimation of Acebrophylline, Montelukast, and Fexofenadine in Bulk and Pharmaceutical Dosage Forms 2023-03-03T04:52:40+00:00 Sreedevi Adikay Mounika Bhavanasi Sai Sruthi Kaveripakam <p style="text-align: justify;"><strong>Introduction:</strong> The goal of the current work is to create an RP-HPLC method for the quantitative analysis of Acebrophylline, Montelukast, and Fexofenadine in Pharmaceutical dosage form. <strong>Materials and Methods:</strong> Chromatographic separation of Acebrophylline, Montelukast and Fexofenadine was executed on Waters Alliance-e2695, by using Hyper clone 5μ BDS C<sub>18</sub> 130A (250 x 4.6mm) column and the mobile phase consisting of Methanol: Ammonium formate adjusted to pH-6 and ortho phosphoric acid (70:30).

The envelope protein (E), which facilitates JEV entrance into the host cell, has been chosen as a possible molecular aim for therapeutic progress in this work.<strong> Materials and Methods: </strong>The 3D structure of E protein was retrieved from RCSB PDB (id: 3P54). The sdf files of four lead molecules namely etoposide, netropsin, nogalamycin, and novobiocin were downloaded from the PubChem and used for molecular docking against JEV E protein. We then assessed the fluorescence emission intensity of JEV alone and JEV bound to novobiocin at 280–500 nM to confirm the inhibition of JEV by Novobiocin. The secondary structure of JEV was ascertained by measuring its CD spectra. The CD spectra of JEV were examined as a function of temperature to evaluate the protein constancy. <strong>Results</strong>: Our docking and fluorescence emission spectra results showed that JEV E pro has good binding preference for novobiocin among these four test compounds. Moreover, fluorescence emission spectra of JEV E protein with novobiocin also revealed the 5 μM concentration is an effective novobiocin concentration to inhibit the activity of target protein. One top ranked lead molecule namely novobiocin with strong binding affinity (-8.574 Kcal/mol) to JEV E protein was known based on binding energy. Results of the CD Spectra made it quite evident that there is no random coil. Peaks in the negative range (troughs) at 210–230 nm in the CD spectra indicate that JEV has a secondary structure rich in helices. The data unambiguously show that there is no appreciable variation in the JEV curves. <strong>Conclusion: </strong>Conclusion of the current work offer a thorough understanding of how the JEV E protein is inhibited and provide information that will help novobiocin be developed as a therapeutic drug against JEV E protein in certain viral diseases.</p> 2023-02-02T00:00:00+00:00 ##submission.copyrightStatement## A Pilot Study on Medication Adherence, Patient Satisfaction, KAP and Quality of Life of Hypertensive Patients 2023-03-03T04:52:41+00:00 Dilipkrishnan K Gopalakrishnan G <p style="text-align: justify;"><strong>Aim:</strong> The present study was designed as a pilot study to assess the prevalence and reasons for occurrence of hypertension and identify the various treatment options prescribed and to determine the patients’ awareness and adherence to the treatment. <strong>Materials and Methods:</strong> An institution based cross-sectional study for a period of one month was conducted among the patients of Department of General Medicine, DM WIMS Multispecialty Hospital, Wayanad, Kerala by using standard questionnaires. 51 patients who meet the inclusion criteria were enrolled in the study. Well-structured questionnaires and standard tools such as Patient Satisfaction Scale (SAPS), Hill-Bone medication adherence scale (HB-MAS), WHOQOL-BREF were utilized to collect the data. Collected data was scrutinized by using Statistical Package for Social Sciences (SPSS version 15.0). Student t-test and one-way ANOVA were employed to test for associations at 95% confidence interval. P&lt;0.05 were considered significant. <strong>Results: </strong>The Results indicated rise of prevalence of hypertension in rural regions. Middle ged male group was mostly affected. Majority of the participants were affected with Grade III hypertension for more than five years and also affected with other chronic illness. All the study subjects were treated with multi-therapy regimen with dose frequency of BID. Results showed a lesser level of treatment satisfaction, medication adherence, KAP and quality of life of study population. <strong>Conclusion: </strong>The results strongly supported the need of the patient counselling by clinical pharmacists to improve the analysed parameters. Hopefully, future study with larger sample size with proper patient counselling could provide a significant outcome.</p> 2023-03-02T00:00:00+00:00 ##submission.copyrightStatement## Evaluation of Knowledge, Attitude and Practice towards Hypothyroidism among Population in Moradabad District: A Pilot Study 2023-03-07T07:18:14+00:00 Rahul Arora Piyush Mittal Jyoti Trivedi Anurag Verma <p style="text-align: justify;"><strong>Introduction:</strong> Thyroid problems are thought to be a widespread health problem in India, as they are across the world. However, there is a lack of data on these patients' knowledge, attitude, and practices (KAP). <strong>Objectives: </strong>The goal of this study is to create and validate a questionnaire and to assess the knowledge, attitude, and practices of population towards hypothyroidism. <strong>Materials and Methods:</strong> There were two phases to the questionnaire: development and validation. A literature review and evaluation are all part of the development phase. The validation phase entailed determining the questionnaire's suitability by evaluating factors such as clarity, simplicity, accuracy, and relevance using scores provided by lingual experts and Institutional ethical committee members. <strong>Results: </strong>The current cross-sectional study was conducted on 50 random participants over the age of 20 live in Moradabad District. Cronbach's alpha was used to determine the consistency of replies to individual items and the entire questionnaire. Questionnaire's overall standardized alpha value was 0.821, which is an excellent Cronbach score and suggests good homogeneity. The self-structured questionnaire comprises of KAP based 30 yes, no, or don't know items. The majority of the participants were between the ages of 30-40. 24% were unable to identify the thyroid gland's primary activities. 86% agreed that hypothyroidism is inherited and that they should monitor their thyroid levels on a frequent basis. In terms of adherence, 80% of the individuals were found to be following their treatment plan.</p> 2023-03-02T00:00:00+00:00 ##submission.copyrightStatement## Prevalence of Depression and Anxiety among General Population during COVID-19 Second Wave in Saudi Arabia 2023-03-03T04:52:41+00:00 Ahlam Furayhan Althobaiti Shuruq Hamdan Alshalawi Atheer Atallah Alqurashi Waad Faris Altowairqi Hajer Mubark Alsulami Shaheen Sultana <p style="text-align: justify;"><strong>Introduction: </strong>Coronavirus 2019 (COVID-19) Pandemic had serious impact on people’s mental health in the 21<sup>st</sup> century.
